I purchased a Z425 last August, at this time it has about 100 hours on it. I really don't use it that often because it isn't a commercial grade mower. Well I have had it in the shop 10 times and it is currently there now b/c of a needle sticking and the solenoid can't pull it back out because it is seizing in there. It only will run for 5 to 10 hours before it has to be taken back in! I have had them replace the solenoid and the carburetor to no avail. Well against my better judgment I went to John Deere and purchased a John Deere G15 Commercial WB with a mulching kit and jungle wheels. I got it to my first stop today and made three passes and the right wheel, wheel assembly, and brake came off!!! I had only been operating this machine for 5 minutes top, come on John Deere where is the pride in craftsmanship that you guys have been known for for years? As expected I went straight back and asked them for my check back and that I would kindly go somewhere else and purchase a product that I can count on to produce for me! Have any of you had anything similar happen to you?
